76 years after they were written, a collection of letters from the Second World War caught the attention of the 34-year-old historian and French author Clément Horvath: In the summer of 1944, a British soldier mentioned his nephew Joe, posted as missing in action shortly after the D-Day landings... What had happened to him? The author turned filmmaker embarked on a long investigation full of twists and turns, from the archives to the former battlefields of the little-known and disastrous Operation Epsom. Using rare archive footage, exclusive interviews (veterans, witnesses, experts...) and re-enactment scenes shot where the real action took place, his self-produced documentary ''The Missing Highlander'' tells the true story of Joe, gives an insight into the research work that led to the discovery of his fate, and pays tribute to the men and women who fell for our freedom.—Paul Woodadge
